GRAIN-BOX FOB DBILLS OR THE LIKE.

Specification of Letters Patent.

Patented Jan. 14, 1919.

Application filed September 16, 1915. Aerial No. 50,9l6.

To all whom it may concern:

Be it known that T, GHARLEsW. ROBINSON, a citizen of the United States, residing at Hamilton, in the county of Wentworth and Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Grain-Boxes for Drills or the like, of which the following is a full, clear, and exact specification.

My invention relates drills or the like.

lit has for its object to provide an improved grain box, and particularly to provide a grain box adapted to export shipment, the same being of such an improved character that it may be readily knocked down for shipment and packed very compactly, the parts of the grain box, for instance, being adapted to be placed in the open spaces in the frame or other shipping packages. A further object of my invention is to provide an improved grain box of simplified construction which may be very readily assembled or knocked down, as desired, and which, when assembled, is exceedingly strong and well adapted to service conditions. I attain these objects by an improved construction of grain box in which the parts are of improved form and are connected together and disposable one with respect to the other when knocked down in an improved manner, all as hereinafter more fully set forth.

Tn. the accompanying drawings T have illustrated one embodiment which my invention may assume in practice.

In these drawings:

Figure 1 shows a partial end view grain box with the cover raised.

Fig. 2 is a transverse sec ional view of the grain box with the cover closed, the box being shown on its frame or support.

Fig. 3 is a side elevation of a grain box showing the support in section and the bracing means for the box.

Fig. 4 is a detail side view of one end of the box.

Fig. 5 is a plan view showing connected to the cover.

The box is carried upon a frame in form of parallel angle bars 1 and stands upright thereon in a well known manner. As shown, it comprises a plurality of longitudinally disposed side members 2, end members 3 and a cover or top A.

to grain boxes for of the the means the The side members 2 are preferably formed of sheet metal and provided with longitudinally disposed, outwardly extending, nestable strengthening ribs 5 and rolled upper and lower edges 6 and 7. Extending through these rolled edges 6 and 7 of the side members 2 are longitudinally disposed rods 8 which pass through the end members 3 and are removably attached thereto by suitable nuts. As shown, these side members 2 are also connected to one another at points between their ends by transversely disposed braces 9 which are removably attached thereto by nut and bolt connections 10.

The end members 3 are preferably in the form of castings, in outline at least, though sheet metal inserts ends proper if desired. As shown, the ends of the side members 2 are preferably received within and rest against suitable flanges 11 formed on the edges of the members 3. It will also be noted that the end members 3 are provided with depending legs 12 which are removably attached by nut and bolt connections 13 to the supports 1 and that in addition to the rods 8, the end mem bers 3 are connected by a lower longitudinally disposed tie or bracing rod 14: which is removably attached thereto by nuts 15 and is provided with a bent-down portion 16 in its center which passes under suitable supplemental supports 17, the latter being attached to a cross frame member 18 carried on the members 1 and extending outward beneath the box. lit is also to be noted that the side members 20f the box are braced by suitable additional braces 19, preferably attached thereto by certain of the same nut and bolt connections 10 which attach the inner braces 9, the lower ends of the braces 19 being removably attached to certain of the supports 17 by means of nut and bolt connections 20.

The cover A is also preferably'formed of sheet metal and provided with an arch 21, reinforced at 22, 23, the edges of this cover preferably being rolled at 24, similar to the edges of the sides 2, and receiving additional rods 25, 26, similar to the rods 8, one of the rods being similarly attached to the end members 3 and forming a pivot for the cover, while the other acts as a reinforcing or stifi'ening member for the opposite edge of the cover. As shown, the cover is also connected through a link connection 27, 28

may be used to form the.

with upstanding lugs on a cross member 29 removably attached at 30 to the side members 2 and-extending across the top of the box, the link 27 being pivoted at 31 to the cover 4, While the link 28 is pivoted at one end at 32 to the link 27 and at its opposite end at 33 to the member 29, a lug 34: being provided on the link 28 in such a manner as to hold the links against flexing in one direction When the cover is open.

It will be noted that in my improved construction the'box, when assembled, is exceed-' ingly light, the sides and top being made of sheet metal. It will further be noted that the box is securely braced upon the frame in such a manner as to provide a rigid construction not susceptible to Warping or strains in service, the braces 9, 14 and 19 acting-to tie the box securely to its supports. It is also to be noted that when desired the parts of the box may be knocked down and thelatter removed from its support upon releasing the longitudinal rods from the end members and removing the braces 9 and 19. By such a construction it has been found possible to eliminate entirely the separate grain box package which has heretofore been considered necessary, thus eliminating not only theexpense of the lumber used in crating the same, the labor involved in makingthe crate, packing, covering and stenciling the same, but also the extra freight charges which in export shipments are figured by the cubic foot and usually total a very considerable amount.

While I have in this application specifically described one embodiment which my invention may assume in practice, it is, of course, to be understood that the same is used for purposes of illustration and that the in vention may be embodied in other forms without departing from its spirit.

What I claim as my invention and desire to secure by Letters Patent is:

1. In combination, a support, grain box end members carried thereon, side members disposed between said end members, longitudinally disposed rods operatively c0114 nected to said side members and removably attached to said end members, a supplemental longitudinally disposed rod removably attached to said end members, and a cover carried on said rod.

2. I11 combination, a support comprising a plurality of supporting members, grain box end members carried on certain of said members, side members disposed between said end members, longitudinally disposed rods connected to said side members and removably attached to said end members, and a longitudinally disposed tie rod disposed beneath the box connected to said end 1nembers and disposed beneath certain of said supporting members.

In combination, a support, grain box end members carried thereon, side members disposed between said end members and removably attached thereto, a transverse member bridging the space between the upper edges of said side members and removably attached thereto, a cover pivotally mounted on one of said side members, and means operatively connected between said transverse member and said cover for limiting the movement of the latter.

4. In combination, a support comprising a plurality of frame members, grain box end members carried on certain of the same, grain box side members disposed between said end members, longitudinally disposed rods connected to said side members and removably attached to said end members, a tie rod removably attached to said end members and disposed beneath certain of said supporting members, and supplemental upstanding bracing members removably attached to said side members and to certain of said supporting members.

5. In combination, a support, grain box end members carried thereon, grain box side members disposed between said end members, longitudinally disposed rods operatively connected to said side members and removably attached to said end members, braces disposed transversely between said side members, means for removably attaching the same thereto, and supplemental upstanding brace members removably attached to said support and attached to said side members by the attaching means for said first men tioned braces.
